Answer:

a+6=10
To find out the number that a is representing, we have to figure out the answer to 10-6. In these types of problems, to find the answer you just do the opposite of what the sign is showing to do in the original equation. When there is an addition symbol, you subtract and vice versa. The same applies to multiplication and division. Because of this, we now know that 10-6=4 so therefore
a=4

Answer:

(x-5)÷y+z
First, you have to plug the numbers in to the variables that are in the equation.
((26)-5)÷(3)+(18)
From here, you have to follow PEMDAS or Parenthesis, Exponents, Multiplication/Division, and then Addition/Subtraction. Here, we see that there are parenthesis, so we deal with that first. 26-5=21.
(21)÷(3)+(18)
Then, we see that there are no exponents, so we go to multiplication/division. We now see that we have to work on the problem 21÷3. The answer to that is 7.
(7)+(18)
Finally, we work with the addition/subtraction. The equation is 7+18. That makes the final answer 25.
A: 25
